Benefits of technology

The invention is about a system that uses ultraviolet light to disinfect and clean the air that is breathed in and out by people wearing protective face masks or patient ventilators. The system is made up of a small, portable cartridge that is inserted into the air hose of the mask or ventilator. The cartridge has a UV light that can kill harmful viruses and bacteria as the air flows through it. The cartridge can be designed in a straight or serpentine style, and the more movements it has, the more compact it can be made. The serpentine design is easier to carry and more ergonomic. Overall, this system helps to keep healthcare workers safe from harm during medical procedures.

Problems solved by technology

For instance, flat baffles that are dimpled over the surface create a more random dispersion of the reflected UV light, which has been shown to increase photon capture by pathogens, and thus increase lethality.

Abstract

An ultraviolet disinfecting cartridge system utilizes an ultraviolet disinfecting cartridge particularly adapted for coupling with a face mask that covers the nose and mouth or to the inhale and exhale tubing of a patient ventilator. The ultraviolet disinfecting cartridge includes multiple UV light emitters that emit UVGI light into the flow channel of the cartridge to neutralize or destroy pathogens. A plurality of baffles may be configured in the flow channel to create a serpentine airflow to increase pathogen exposure time to UV light. A photocatalyst material such as titanium oxide may be configured within the flow channel that is activated by UV light to increase disinfection. An ionizer may be configured proximal to the inlet to produce charged particles that provide disinfection. Any ozone produced may be mitigated by a catalytic converter to a safe level. Inlet and outlet filters may be detachably attachable to the ultraviolet disinfecting cartridge.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a national stage application of PCT / US2021 / 032776, filed on May 17, 2021, which claims the benefit of priority to U.S. patent application Ser. No. 63 / 026,003, filed on May 16, 2020; the entirety of both applications are hereby incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The invention relates an ultraviolet (UV) disinfecting cartridge system comprising an ultraviolet light and ionizing disinfecting cartridge particularly adapted for coupling with a ventilator system, such as to a patient ventilator, along the inhale and exhale ventilator hoses and / or to a face mask that covers the nose and mouth that disinfects ambient air that is drawn through the disinfecting cartridge as an active personal protective equipment (PPE) system that destroys pathogens such as COVID-19 and prevents the spread of pathogens.[0004]Background[0005]The COVID-19 pandemic has created urgent needs ...
